Abstract
The aim of this review article is a comprehensive systematic review of peer-reviewed literature data on the methods for olfactory dysfunction diagnosis in patients with chronic rhinosinusitis with consideration for anatomy and pathomorphology. Additionally, we have assessed the reliability and informative value of various methods. The search was carried out in PubMed, Web of Science and Google Scholar databases using the following keywords: “smell” AND “rhinosinusitis” OR “polyps”. As a rule, the presented methods of olfactory function diagnosis for patients with chronic rhinosinusitis only allow determining of quantitative disorders. It is required to select a universal diagnostic method which will make it possible to determine the location of the olfactory nerve lesion, the quantitative and qualitative impairment of the function taking into account the olfactory nerve fatigue and the time of adaptation.
